You are purchasing 2 pair of Epoch Murphy Sunglasses; one with tortoise frames and polarized green mirror lenses and one with black frames and polarized blue mirror lenses. The Murphy is our take on a classic look. The ultra-lightweight full-frame is a great look for everyone. The arms wrap behind the ear to ensure a great no-slip fit. This is a favorite for active and every day wear. Mirror lenses are constructed by applying a reflective coating to a smoke lens base. These unique products deliver the same protection as smoke lenses but have the added benefits of enhanced color perception while reducing glare -- all due to the addition of the color reflective coating. Ideal for full-sunlight, snow, and water-reflective conditions. Light transmission 10-13% depending on reflective coating applied. Epoch Eyewear is a Veteran owned and operated company. We are proud to be a part of the Veteran community and build a company that provides jobs and great products.
